摘要
针对±800kV直流输电线路带电检修作业中耐张绝缘子串金具攀爬困难的问题,对带电作业现场环境及方式进行分析,根据±800kV线路带电作业的需要,设计了一种具有可转动接头、不同尺寸卡座的带电作业绝缘伸缩平梯。应用结果表明:该平梯的设计确保了作业人员的操作安全,提高了带电作业的效率,满足现场带电作业的要求,具有实用性和创新性。
Aiming at the problem of strain insulator string climbing difficultly in live maintenance working of ±800 kV DC transmission line, analyzes work environment and mode of live working, according to the demands of live working on ±800 kV transmission line, designs a kind of insulating telescopic ladder which has swing joint and different size joint holder. The application result shows that： this design meets the demand of live working, ensures the operation safety of the operators, improves the efficiency of live working, has practicability and innovation.
